any other power adapter.
• Ensure that the VAC ratings match.
• Ensure that you have read the MP252 Regulatory Information, obtained
from www.audiocodes.com/library.
Note: The cabling procedures for the MP252 models are identical and therefore, no
distinction is made between the models in this section. However, for
convenience, this section uses the MP252WDNB model as an example.
The figure below displays a summary of the cabling procedures.
Figure 3-5: Cabling MP252
MP252 Multimedia Home Gateway 34 Document #: LTRT-23504
User's Manual
To cable MP252:
1. Connect MP252 to the Internet. The cabling depends on the Internet connection:
• ADSL: connect the ADSL port (located on the rear panel and labeled ADSL) to the
telephone socket, using an RJ-11 telephone cable.
• WAN Ethernet: connect the LAN4/WAN port (located on the rear panel and
labeled LAN 4/WAN) to an external modem, using a CAT-5 Ethernet cable.
Note: Use minimum 26 AWG wire for cabling the ADSL port to the public switched
telephone network (PSTN).
2. Connect the LAN Ethernet ports (labeled LAN 1 - 4) to your LAN computers, using
RJ-45 CAT-5 Ethernet cables.
3. Connect the telephone ports (labeled Phone 1 - 2) to analog telephones, using RJ-11
telephone cables.
4. Connect MP252 to a standard 110/220 VAC electrical wall outlet, using the supplied
AC/DC power adapter.
When MP252 is powered on, the Status LED is lit. After initialization completes (about two
minutes), this LED changes from red to green. If no power is received by
MP252, press the Power button located on the rear panel to switch it on.
3.3 Mounting
You can place MP252 on a desktop or mount it on a wall. For desktop mounting, MP252
provides integrated rubber feet on its base so that it sits firmly on a desktop. Alternatively,
you can hang your MP252 on a wall, using the supplied MP252 wall-mounting bracket, as
described in this section.
Wall mounting consists of the following main procedural stages:
Preparing the mounting screws on the wall
Hanging the mounting bracket on the wall
Attaching MP252 to the mounting bracket
Before you begin, ensure that you have the following items:
Wall-mounting bracket (supplied)
2 x screws
2 x wall anchors
Screwdriver
Note: When choosing a wall on which to mount MP252, consider cable limitations and
wall structure.
To wall-mount MP252:
1. Prepare the wall-mounting screws:
a. Drill two holes in the wall according to the wall-mounting bracket dimensions. The
vertical distance between the holes should be 83 mm (3.27 inches).
b. Insert a wall anchor into each hole.
MP252 Multimedia Home Gateway 3. Hardware Description
Version 3.4.0 35 June 2011
c. Using a screwdriver, drive screws of the appropriate size into the anchors, leaving
approximately 4 mm (0.16 inches) of the screw head jutting out. This protrusion will
allow you to hang the mounting bracket on the screw head.
Figure 3-6: MP 252 Wall Mount Bracket
2. Hang the mounting bracket on the wall screws:
a. Gently slide the mounting bracket onto the lower screw so that the screw enters the
bracket's bottom screw groove rail. As you lower the bracket onto the screw,
ensure that the upper screw fits into the bracket's top screw groove.
b. Gently pull down on the mounting bracket so that both screw heads sit firmly and
securely in the top notch of the screw grooves.
3. Attach MP252 to the wall-mounting bracket:
a. Three slits at the base (bottom) of MP252 are covered by rubber caps. Remove
these caps.
b. With its rear panel facing the mounting bracket, hold MP252 at an angle and slide
the base of MP252 under the two latches located on the mounting bracket.
c. Align the three slits on the MP252 base with the three protruding humps located on
the front of the mounting bracket. Align the clip holes on either side of MP252 with
the clips on the mounting bracket.
d. While gently pressing down on MP252, press the clips inwards so that the clips
snap into the base of MP252.

4.5.2 Defining Network Objects
Network objects is a method used to logically define a set of LAN hosts, according to one or
more MAC address, IP address, and host name. Defining such a group can assist when
configuring other system rules. For example, you can use network objects to apply security
rules based on host names instead of IP addresses. This may be useful, since IP addresses
change from time to time. Moreover, it is possible to define network objects according to
MAC addresses, making rule application more persistent against network configuration
settings.

7.2 Using the Automatic Dialer for Internet Connection
The Automatic Dialer feature allows the service provider to use one type of pre-configured
MP252 for all the following Internet connection types:
WAN Ethernet (DHCP, LT2P or PPPoE)
WAN ADSL (PPPoE)
In the Private Labeling process, the factory setting is burned with the parameters of the
different dialers. When powered-up at the customer site, MP252 first detects the physical
WAN type (ADSL or Ethernet) and then attempts the relevant WAN connection methods.
The indication for a successful result is connection (i.e., receipt of an IP address) and a ping
test.
This section describes the recommended process for using the Automatic Dialer.
Notes:
• If the Automatic Dialer feature is shipped pre-configured (i.e., enabled),
then MP252 automatically detects the Internet dialer type and therefore,
configuration of the Internet connection is not necessary. However, it is
recommended to manually configure the Internet connection after the
Automatic Dialer process has completed (successfully or not).
• If you manually configure the Internet connection in the Web interface, the
Automatic Dialer feature becomes disabled.
7.2.1 Recommended Configuration
The recommended factory settings for the Automatic Dialer feature are shown below:
(auto_dialer_detect

progress status by checking the MP252 LEDs (see Section 3.1.1.2.2 on page 30).
Notes:
• If the connection is ADSL, the Automatic
Dialer usually connects in the first
iteration (after less than 10 seconds, when configuring manual PVC). In
some cases, the Automatic Dialer may connect in the second iteration (up
to 4 minutes).
• If the connection is WAN Ethernet:
- For DHCP, the connection is fast.
- For L2TP, the connection takes up to ~2 minutes.
- For PPPoE, the connection can take up to ~4 minutes.

7.2.3 Quitting Automatic Dialer for Manual Configuration
If, for any reason, you need to manually configure the Internet connection, you first need to
stop the Automatic Dialer feature and then manually configure the connection, as described
below,
To quit Automatic Dialer and manually configure the Internet connection:
1. Power off the MP252.
2. Disconnect the WAN ADSL or Ethernet cable.
3. Power on the MP252.
4. Wait for the Automatic Dialer process to end (i.e., the Broadband LED stops blinking).
5. Log in to the MP252 Web interface.
6. Manually configure the Internet connection using the 'Quick Setup' screen (see Section
7.1 on page 63). This ensures that the Automatic Dialer feature does not re-activate
itself after the MP252 resets.
Once the MP252 successfully connects to the Internet, it downloads its configuration file from
the server.
Note: The configuration file must include the following parameter to indicate that
Automatic Dialer is no longer needed: auto_dialer_detect/done = 1.

User's Manual
8.1.1 Configuring Proxy Redundancy
The Redundant Proxy feature allows the configuration of a backup SIP proxy server to
increase Quality of Service (QoS). Once this feature is enabled, MP252 identifies cases
where the primary proxy does not respond to SIP signaling messages. In these cases,
MP252 registers to the redundant proxy and seamlessly continues normal functionality,
without any noticeable connectivity failure or malfunction with the primary proxy.
The Redundant Proxy feature includes two operational modes:
Asymmetric mode: This mode assigns the primary proxy a higher priority for
registration over the redundant proxy. Once MP252 is registered to the primary proxy, it
sends keep-alive messages (using SIP OPTIONS messages) to the primary proxy. If
the primary proxy does not respond, MP252 registers to the redundant proxy, but
continues sending keep-alive messages to the primary proxy. If the primary proxy
responds to these keep-alive messages, MP252 re-registers to the primary proxy.
Symmetric mode: In this mode, both proxies are assigned the same priority for
registration. Once MP252 is registered to a proxy (primary or redundant), it sends
keep-alive messages to this proxy. MP252 switches proxies only once the proxy to
which it has registered does not respond.
In both modes, the following applies:
If MP252 is not registered (i.e., if the proxy server - redundant or primary - to which
MP252 currently tries to register does not respond), MP252 attempts to register to an
alternative proxy. These attempts continue until MP252 successfully registers.
If this feature is enabled and you reboot MP252, it registers to the last proxy to which it
was trying to register (not necessarily to the primary proxy).
To configure proxy redundancy:
1. From the menu bar, click the Voice Over IP menu; the Signaling Protocol tab screen
appears.
2. Define a primary proxy server (under the SIP Proxy and Registrar group):
a. Select the ‘Use SIP Proxy’ check box.
b. In the 'Host Name or Address' field, enter the primary proxy's IP address.
c. In the 'Proxy Port' field, enter the primary proxy's port number.
3. Define a redundancy proxy server (under the SIP Proxy and Registrar group):
a. Select one of the following check boxes: 'Use SIP Registrar' or 'Use SIP Proxy IP
and Port for Registration'.
a. Select the 'Use Redundant Proxy' check box.
b. In the 'Redundant Proxy Address' field, enter the redundant proxy's IP address or
DNS name.
c. In the 'Redundant Proxy Port' field, enter the redundant proxy's port number.

MP252 Multimedia Home Gateway 8. Configuring VoIP Parameters
Version 3.4.0 87 June 2011
Table 8-2: Dialing Tab Parameters Description
Parameter Description
Dialing Parameters
Dialing Timeout
Defines the duration (in seconds) of allowed inactivity between dialed digits.
When you work with a proxy, the number you have dialed before the dialing
process has
timed out is sent to the proxy as the user ID to be called. This is
useful for calling remote parties without creating a speed dial entry
(assuming the remote party is registered with the proxy).
Phone Number Size Defines the maximum length of shortcu
t numbers that you can enter and the
maximum number of digits that you can dial.
Enabled dialing
complete key
When selected (default), you can define a key that when pressed forces
MP252 to make a call to the dialed digits even if there is no match in the
dial
plan or digit map. The key is defined in the ‘Complete dialing key’ field, which
appears when this parameter is selected.
Note: This parameter appears only in 'Advanced' mode.
Complete dialing key Defines the key that when pressed forces MP252 to m
ake a call to the dialed
digits even if there is no match in the dial plan or digit map. The default value
is the pound (#) key.
Note:
This parameter is available only if the ‘Enabled dialing complete key’ is
selected.
Dial Tone Timeout Defines the
duration of the dial tone (in seconds). If the limit is exceeded, the
dial tone stops and you a reorder tone is played.
Reorder Tone Timeout
Defines the duration (in seconds) of the reorder tone. The reorder tone is
played, for example, when MP252
receives a SIP 486 response. If the limit is
exceeded, the reorder tone stops and a howler tone is played.
Note: This parameter appears only in 'Advanced' mode.
Unanswered call
timeout
Defines the timeout before MP252 automatically sends a SIP CANCEL
message. When MP252 makes a call and the other side doesn’t answer,
MP252 sends a CANCEL message after this timeout.
Note: This parameter appears only in 'Advanced' mode.
Howler Tone Timeout Defines the duration (in seconds) of the howler
tone. If the limit is exceeded,
the howler tone stops playing. The howler tone informs a user that the user's
phone has been left in an off-hook state.
Note: This parameter appears only in 'Advanced' mode.
Flash min Defines the duration (in ms) after which you can begin to perform a flash
hook.
Flash max Defines the maximum duration (in ms) that the flash hook button can be
pressed, after which the call is disconnected.
Enable Re-Answer
Timeout
When selected, the ‘Re-Answer Timeout’ field appears, allowing you to
define the timeout after on-hooking an active call and then off-hooking it
again. Once this time expires and the phone has not been off-
hooked again,
the call is disconnected.
Send DTMF Out-Of-
Band
Defines how the DTMF tones are sent (‘Inband’, ‘RFC2833’, or ‘Via SIP’).
DTMFs are the tones generated by your telephone's keypad.
Note: This parameter appears only in 'Advanced' mode.
MP252 Multimedia Home Gateway 88 Document #: LTRT-23504
User's Manual
Parameter Description
Digit Map Defines formats (or patterns) for the dialed number. A match to one of the
defined patterns terminates the dialed number. For an explanation on digit
map syntax, see Section 8.2.1 on page 88.
Note: This parameter appears only in 'Advanced' mode.
Dial Plan Defines patterns to translate to specific SIP destination addresses. For dial
plan syntax rules for patterns entered to the left of the '=' sign, see Section
8.2.1 on page 88.
Note: This parameter appears only in 'Advanced' mode.
Key Sequence
Flash keys sequence
style
Defines the key sequence with the flash button:
‘Flash only’ (default) = uses only the phone's Flash button. There are
three scenarios:
During an existing call, if the user presses Flash, the call is put on
hold, a dial tone is heard and the user is able to initiate a second call.
Once the second call is established, on-hooking transfers the first
(held) call to the second call.
During an existing call, if the user presses Flash, the call is put on
hold and a dial tone is heard. The user can initiate a second call and
establish a 3-way conference by again pressing Flash after the
second call is initiated.
During an existing call, if a cal
l comes in (call waiting), pressing Flash
puts the active call on hold and answers the waiting call; pressing
Flash again toggles between these two calls.
‘Flash + digits sequence’ = Flash button with a key sequence:
Flash + 1 holds a call or toggles between two existing calls.
Flash + 2 makes a call transfer.
Flash + 3 establishes a 3-way conference.
'Send Flash Hook Via SIP' = you can modify the SIP INFO message that
is sent upon Flash. You can change the Content Type header field and
Message Body field.
Note: This parameter appears only in 'Advanced' mode.
SIP INFO Header
When the key sequence is set to 'Send Flash Hook Via SIP', you can modify
the Content Type header field of the SIP INFO message.
For example: "application/broadsoft; version = 1.0"
Note: This parameter appears only when the ‘Flash keys sequence style’
field is set to 'Send Flash Hook Via SIP'.
SIP INFO Body
When the key sequence is set to 'Send Flash Hook Via SIP', you can modify
the Message Body field of the SIP INFO message.
For example: " event flashhook"
Note: This parameter appears only when the ‘Flash keys sequence style’
field is set to 'Send Flash Hook Via SIP'.
8.2.1 Syntax for Digit Maps and Dial Plans
Digit maps and dial plans are defined using special syntax rules, configured in the 'Dialing'
screen (see Section 8.2 on page 85).
Digit Maps: A phone's digit map allows MP252 to know when an entered telephone
number is complete and therefore, when it should initiate the call. If the phone digit map
is defined incorrectly, MP252 might start to dial before the telephone user has entered
MP252 Multimedia Home Gateway 8. Configuring VoIP Parameters
Version 3.4.0 89 June 2011
all the required digits. A digit map is defined either by a (case insensitive) "string" or by a
list of strings. Each string in the list is an alternative numbering scheme, specified either
as a set of digits or as an expression over which MP252 attempts to find a shortest
possible match. The syntax that can be used in each numbering scheme is described in
the table below.
Dial Plans: A dial plan translates specific patterns into specific SIP destination
addresses. For example, dial plan rule "4xxx=Line_\\\@10.1.2.3" sends a dialed
number consisting of the digit “4” followed by any three digits to IP address 10.1.2.3.
The syntax of the pattern on the left of the '=' sign is described in the table below.
Table 8-3: Dial Plan (for Left of '=' Sign) and Digit Map Syntax
Type Syntax
Digit A digit from "0" to "9".
DTMF A digit, or one of the symbols "A", "B", "C", "D", "#", or "*". Extensions may be
defined.
Wildcard The symbol "x" which denotes any digit ("0" to "9").
Range One or more DTMF symbols enclosed between square brackets ("[" and "]").
Sub-range Two digits separated by a hyphen ("-") which matches any digit between and
including the two. The subrange can only be used inside a range construct, i.e.,
between "[" and "]".
Position
A period (".") which matches an arbitrary number, including zero, of occurrences of
the preceding construct.

Parameter Description
Quality of Service Parameters
Type of Service (Hex) This is a part of the IP header that defines the type of routing service to be
used to tag outgoing voice packets originated from MP252. It is used to
inform routers along the way that this packet should get specific QoS. Leave
this value as 0xb8 (default) if you are unfamiliar with the Differentiated
Services IP protocol parameter.
Codecs

th
Codec Defines the voice codec. For more information, see 8.3.1 on page 91.
8.3.1 Configuring Codecs
Codecs define the method of relaying voice data. Different codecs have different
characteristics, such as data compression and voice quality. For example, G.723 is a codec
that uses compression, so it is good for use where bandwidth is limited but its voice quality is
not as good compared to other codecs such as the G.711.
8.3.1.1 Supported Codecs
To make a call, at least one codec must be enabled. Moreover, all codecs may be enabled
for best performance. When you start a call to a remote party, your available codecs are
compared against the remote party's to determine the codec used. The priority by which the
codecs are compared is according to their order of appearance in the table (descending
order). To change the priorities, rearrange the codecs in the required order.
If there is no codec that both parties have made available, the call attempt fails. Note that if
more than one codec is common to both parties, you cannot force which of the common
codecs that were found are used by the remote party's client. If you do wish to force the use
of a specific codec, leave only that codec checked.
8.3.1.2 Packetization Time
The Packetization Time is the length of the digital voice segment that each packet holds. The
default is 20 millisecond packets. Selecting 10 millisecond packets reduces the delay but
increases the bandwidth consumption.
8.4 Configuring Voice and Fax

MP252 Multimedia Home Gateway 8. Configuring VoIP Parameters
Version 3.4.0 95 June 2011
Parameter Description
CED Transfer Mode
By Fax Relay: When MP252 is the receiver side, Switch to Fax relay is
enabled upon CED. This allows a high reliable fax-over-IP call
establishment at the beginning of CED tone.
In Voice Or PCM Bypass: When MP252 is the receiver side, to avoid
possible conflicts with low-
speed modems, the CED (ANS) relay by FoIP
protocol may be disabled by setting the CED transfer mode to ‘In Voice
Or PCM Bypass’. In this case, MP252 does not initiate the Fax Relay on
detecting CED tone in absence of CNG, but switches to VBD or remains
in voice mode (depends on the Modem Transport Mode). MP252
switches to
FoIP later when it defines exactly that a monitored call is the
fax call (CED and CND or V.21 Preamble).
Enable CNG Detection
Enables detection of the fax CNG signal. When the local fax machine
connected to MP252 receives a fax, MP252
switches to T.38 fax relay upon
detection of the CED signal from the remote fax. If the local fax machine
sends a fax, MP252 switches to T.38 only after detecting the CNG signal
from the local side and the CED signal from the remote side. If this check bo
x
is selected, MP252 switches to T.38 relay immediately upon detection of the
CNG signal from the local side, without waiting for the CED signal from the
remote side. The default is disabled.
Switch To Fax Only By
The Answering Side
Typically, switching to fax mode is the responsibility of the answering side.
However, in some cases, the sending machine can also switch to fax mode.
If this check box is marked, the sending machine does not switch to fax, but
allows the answering side to detect the fax and switch to fax mode.

8.6 Configuring Line Settings
Before you can make phone calls, you need to configure lines. Lines are SIP logical ID
numbers (i.e., telephone numbers), which are registered to the SIP proxy server, and for
which you are charged for calls you make on it.
MP252 supports two line-configuration modes:
One-Line Configuration: In this mode, only one line is configured to represent all the
physical telephone extensions on MP252 (i.e., two analog phones and five DECT
handsets):
• When you receive an incoming call, all the extensions on the line ring, and you can
answer from any one of them. When you do answer, the other extensions stop
ringing.
• If you receive another incoming call when you already have an established call on
one extension, all the idle extensions ring, and the busy extension hears a call
waiting tone.
• You can make outgoing calls from any of the extensions.
• You can make multiple concurrent calls (i.e., each extension makes a call to a
different destination and at the same time).
Three-Lines Configuration: In this mode, three lines can be configured:
• Line 1 for the analog telephone connected to the MP252 port labeled Phone 1
• Line 2 for the analog telephone connected to the MP252 port labeled Phone 2
• Line 3 for all the DECT handsets (up to five)
To configure lines:

MP252 Multimedia Home Gateway 11. Quality of Service
11 Quality of Service
Network-based applications and traffic are growing at a high rate, producing an
ever-increasing demand for bandwidth and network capacity. For obvious reasons,
bandwidth and capacity cannot be expanded infinitely, requiring that bandwidth-demanding
services be delivered over existing infrastructure, without incurring additional, expansive
investments.
The next logical means of ensuring optimal use of existing resources are Quality of Service
(QoS) mechanisms for congestion management and avoidance. QoS refers to the capability
of a network device to provide better service to selected network traffic. This is achieved by
shaping the traffic and processing higher priority traffic before lower priority traffic.
As QoS is dependent on the "weakest link in the chain", failure of but a single component
along the data path to assure priority packet transmission can easily cause a VoIP call or a
Video on Demand (VoD) broadcast to fail miserably. QoS must therefore obviously be
addressed end-to-end.
The following are the potential bottleneck areas that need be taken into consideration when
implementing an end-to-end QoS-enabled service.
The Local Area Network: LANs have finite bandwidth, and are typically limited to 100
Mbps. When given the chance, some applications consume all available network
bandwidth. In business networks, a large number of network-attached devices can lead
to congestion. The need for QoS mechanisms is more apparent in wireless LANs,
where bandwidth is even more limited (typically no more than 20 Mbps on 802.11g
networks).
The Broadband Router: All network traffic passes through and is processed by the
broadband router. It is therefore a natural focal point for QoS implementation. Lack of
sufficient buffer space, memory or processing power, and poor integration among
system components can result in highly undesirable real-time service performance. The
only way to assure high QoS is the use of proper and tightly-integrated router operating
system software and applications, which can effectively handle multiple real-time
services simultaneously.
The Broadband Connection: Typically, the most significant bottleneck of the network,
this is where the high speed LAN meets limited broadband bandwidth. Special QoS
mechanisms must be built into routers to ensure that this sudden drop in connectivity
speed is taken into account when prioritizing and transmitting real-time service-related
data packets.
The Internet: Internet routers typically have a limited amount of memory and bandwidth
available to them, so that congestions may easily occur when links are over-utilized,
and routers attempt to queue packets and schedule them for retransmission. One must
also consider the fact that while Internet backbone routers take some prioritization into
account when making routing decisions, all data packets are treated equally under
congested conditions.
Note: For recommended QoS configuration see Section 11.7 on page 128.

11.2 Traffic Shaping
Traffic Shaping is the solution for managing and avoiding congestion where a high speed
LAN meets limited broadband bandwidth. A user may have, for example, a 100 Mbps
Ethernet LAN with a 100 Mbps WAN interface router. The router may communicate with the
ISP using a modem with a bandwidth of 2 Mbps. This typical setup makes the modem,
having no QoS module, the bottleneck. The router sends traffic as fast as it is received, while
its well-designed QoS algorithms are left unused. Traffic shaping limits the bandwidth of the
router, artificially forcing the router to be the bottleneck.
A traffic shaper is essentially a regulated queue that accepts uneven and/or bursty flows of
packets and transmits them in a steady, predictable stream so that the network is not
overwhelmed with traffic.
While Traffic Priority allows basic prioritization of packets, Traffic Shaping provides more
sophisticated definitions such as:
Bandwidth limit for each device
Bandwidth limit for classes of rules
Prioritization policy
TCP serialization on a device
You can also define QoS traffic shaping rules for a default device. These rules are used on a
device that has no definitions of its own. This enables the definition of QoS rules on Default
WAN, for example, and their maintenance even if the PPP or bridge device over the WAN is
removed.
MP252 also supports dynamic traffic shaping during a call. Traffic shaping is critical in
residential VoIP gateways because of the bottleneck created in the ADSL or Cable modem,
mainly in the upload direction. Dynamic traffic shaping ensures a minimum bandwidth for
VoIP calls. Without dynamic traffic shaping, traffic shaping limits the bandwidth at all times,
even if the user is not making a VoIP call and therefore, the service provider needs to
configure the QoS traffic shaping transmit (Tx) bandwidth according to the user's specific
upload bandwidth. Configuring a lower value results in a lower upload bandwidth (not only
during VoIP calls).
Dynamic traffic shaping enables the service provider to configure two upload traffic shaping
bandwidth parameters:
"Tx Bandwidth" - for all traffic
"Tx Bandwidth during Call" - for VoIP calls
MP252 normally uses the "Tx Bandwidth" value. When the user makes a VoIP call (i.e. any
phone/s connected to MP252 is ringing or off-hook), MP252 switches to use the "Tx
Bandwidth during Call" value.
11.2.1 Device Traffic Shaping
The procedure below describes how to configure traffic shaping.
To add a traffic shaping device:
1. From the menu bar, click the QoS menu, and then click the Traffic Shaping tab.
MP252 Multimedia Home Gateway 116 Document #: LTRT-23504
User's Manual
Figure 11-2: Quality of Service – Traffic Shaping Screen
2. Click the New icon; the 'Add Device Traffic Shaping’ screen appears.
Figure 11-3: Add Device Traffic Shaping Screen
3. From the ‘Device’ drop-down list, select the device for which you want to shape traffic.
The list includes all interfaces (e.g., All LAN Devices, All WAN Devices) and VPNs such
as PPoE, PPTP and L2TP (if defined). For example, select 'WAN Ethernet', and then
click OK; the ’Edit Device Traffic Shaping’ screen appears.
Figure 11-4: Edit Device Traffic Shaping Screen
MP252 Multimedia Home Gateway 11. Quality of Service
Version 3.4.0 117 June 2011
4. Under the Tx Traffic Shaping group, from the ‘Tx Bandwidth’ drop-down list, select
‘Specify’ and define the MP252’s maximum transmission bandwidth rate in the
corresponding field. The purpose is to limit the bandwidth of the WAN interface to that of
the weakest outbound link, for instance, the DSL speed provided by the ISP. This forces
MP252 to be the network bottleneck, where sophisticated QoS prioritization can be
performed. If the device’s bandwidth is not limited correctly, the bottleneck is an
unknown router or modem on the network path, rendering MP252 QoS useless. To
configure unlimited bandwidth, select ‘Unlimited’.
5. Under the Rx Traffic Policing group, from the ‘Rx Bandwidth’ drop-down list, select
‘Specify’ and define the MP252’s maximum receive bandwidth rate in the corresponding
field. This limits MP252’s bandwidth receipt rate to that of the DSL modem.
6. From the ‘TCP Serialization’ drop-down list, select whether to enable TCP serialization.
The screen refreshes, displaying the ’Maximum Delay’ field. This allows you to define
the maximum allowed transmission time frame (in milliseconds) of a single packet. Any
packet that requires a longer time to be transmitted is fragmented to smaller sections.
This avoids transmission of large, bursty packets that may cause delay or jitter for
real-time traffic such as VoIP.
7. Select the ‘Enable Dynamic Traffic Shaping’ check box if you want to configure traffic
shaping specifically for VoIP calls (see Section 11.2 on page 115). When selected, the
‘Tx Bandwidth During VoIP Call’ field appears. Enter the bandwidth for VoIP calls.
MP252 normally uses the "Tx Bandwidth" parameter value. When the user makes a
VoIP call (i.e. any phone connected to MP252 is ringing or off-hook), MP252 switches to
use the "Tx Bandwidth during Call" parameter value.
11.2.2 Shaping Classes
The bandwidth of a device can be divided to reserve constant portions of bandwidth to
user-defined traffic types. Such a portion is known as a Shaping Class. When not used by its
user-defined traffic type or owner (for example, VoIP), the class is then available to all other
traffic. However when needed, the entire class is reserved solely for its owner. Moreover, you
can limit the maximum bandwidth that a class can use even if the entire bandwidth is
available.
When a shaping class is defined for a specific traffic type, two shaping classes are created.
The second class is the 'Default Class', responsible for all the packets that do not match the
defined shaping class or any other classes that may be defined on the device. This can be
viewed in the Class Statistics screen.
To add a shaping class:
1. From the menu bar, click the QoS menu, and then click the Traffic Shaping tab.
2. Click the Edit icon corresponding to the added Device (e.g., WAN); the 'Edit Device
Traffic Shaping' screen appears.
3. Under the Tx Traffic Shaping group, click the New icon; the 'Add Shaping Class'
screen appears.
Figure 11-5: Add Shaping Class Screen
4. In the ‘Name’ field, enter a name for the class, and then click OK; the 'Edit Device Traffic
Shaping' screen appears.
MP252 Multimedia Home Gateway 118 Document #: LTRT-23504
User's Manual
5. Edit the newly added shaping class, by clicking the corresponding Edit icon; the 'Edit
Shaping Class' screen appears.
Figure 11-6: Edit Shaping Class
6. In the ‘Name’ field, modify the class name, if required.
7. From the ‘Class Priority’ drop-down list, select the priority level for the class, where zero
is the highest and seven the lowest.
8. In the ‘Bandwidth’ field, define the bandwidth for the class:
• Reserved: reserved (i.e., guaranteed) bandwidth (Committed Information Rate /
CIR) in kbps.
• Maximum: specify the maximum bandwidth
9. From the ‘Policy’ drop-down list, select the policy for routing packets within the class:
• Priority: Priority queuing uses multiple queues so that traffic is distributed among
queues based on priority. This priority is defined according to packet priority, which
can be defined explicitly by a DSCP value or an 802.1p value.
• FIFO: First In First Out. This priority queue ignores any previously-marked packet
priority.
• Fairness: The fairness algorithm ensures no starvation by granting all packets a
certain level of priority.
• RED: Random Early Detection. Utilizes statistical methods to drop packets in a
‘probabilistic’ way before queues overflow. Dropping packets in this way slows a
source down enough to keep the queue steady and reduces the number of packets
that would be lost when a queue overflows and a host is transmitting at a high rate.
10. From the ‘Schedule’ drop-down list, select the scheduler rule (defined in Section 4.5.1
on page 47) that defines the time segments during which the class can be active. By
default, the class is always active.
11. Click OK to save your settings.
11.2.2.1 Class Rules
Class rules define which packets belong to the class. Without class rules, the shaping class
has no effect. Each class can have outbound and inbound rules for outgoing and incoming
traffic respectively. For example, you can define that all outgoing packets from computer A in
your LAN belong to your VoIP class. These packets are limited to the class settings
(bandwidth, schedule, etc.). In addition, you can define the traffic protocol and priority for
each rule (this is not mandatory as in Traffic Priority rules).
11.2.2.1.1 Inbound and Outbound Data
MP252 Multimedia Home Gateway 11. Quality of Service
Version 3.4.0 119 June 2011
MP252 can control outgoing data easily. It can queue packets, delay them, give precedence
to other packets, or drop them. This helps in resolving upload (Tx) traffic bottlenecks and in
most cases is sufficient. However, in the case of download (Rx) traffic bottlenecks, the ability
to control the flow is much more limited. MP252 cannot queue packets, since in most cases
the LAN is much faster than the WAN and when MP252 receives a packet from the WAN, it
passes it immediately to the LAN.
QoS for ingress data has the following limitations, which do not exist for outgoing data:
QoS can only be applied to TCP streams (UDP streams cannot be delayed)
No borrowing mechanism
When reserving Rx bandwidth, it is strictly taken from the bandwidth of all other classes
MP252 Multimedia Home Gateway 120 Document #: LTRT-23504
User's Manual
In addition, MP252 cannot control the behavior of its WAN (usually the ISP), which may not
have proper QoS handling. Let’s look at a scenario of downloading a large file and surfing the
Internet at the same time. Downloading the file is distinguished by small requests, followed
by very large responses. This may result in blocking HTML traffic at the ISP. A solution for
such a scenario is limiting the bandwidth of low-priority TCP connections (such as file
download).
To add outbound and inbound class rules, see 11.3 on page 120.
Note: The hierarchy of the class rules is determined by the order of their addition to the
class. For example, if your first rule is match packets with any source address,
any destination address, and any protocol to this class; then all packets
traversing MP252 are associated with the specific class. Any rules defined later
do not have any effect.
11.3 Traffic Priority
Traffic Priority allows you to manage and avoid traffic congestion by defining inbound and
outbound priority rules for each device on your MP252. These rules determine the priority
assigned to packets traveling through the device. QoS parameters (DSCP marking and
packet priority) are set per packet, on an application basis.
You can set QoS parameters using flexible rules, according to the following parameters:
Source/destination IP address, MAC address or host name
Device
Source/destination ports
Limit the rule to specific days and hours
MP252 supports two priority marking methods for packet prioritization:
DSCP
802.1p Priority
The matching of packets by rules is connection-based, known as Stateful Packet Inspection
(SPI), using the same connection-tracking mechanism used by the firewall. Once a packet
matches a rule, all subsequent packets with the same attributes receive the same QoS
parameters, both inbound and outbound.
A packet can match more than one rule, and therefore:
The first class rule has precedence over all other class rules (scanning is stopped once
the first rule is reached).
The first traffic-priority (classless) rule has precedence over all other traffic-priority rules.
There is no prevention of a traffic-priority rule conflicting with a class rule. In this case,
the priority and DSCP setting of the class rule (if given) takes precedence.
MP252 Multimedia Home Gateway 11. Quality of Service
Version 3.4.0 121 June 2011
Connection-based QoS also allows inheriting QoS parameters by some of the applications
that open subsequent connections. For instance, you can define QoS rules on SIP and the
rules then apply to both control and data ports (even if the data ports are unknown). This
feature applies to all applications that have ALG at firewall:
Any
User Defined (FTP, HTTP, HTTPS, TFTP, IMAP, PING, POP3, SNMP, SMTP, Telnet,
L2TP, Traceroute or any other protocol)
To set traffic priority rules:
1. From the menu bar, click the QoS menu, and then select the Traffic Priority tab; the
'Traffic Priority' screen appears.
Figure 11-7: Traffic Priority Screen
This screen is divided into two identical groups - ’QoS Input Rules’ and ’QoS Output
Rules’ - for prioritizing inbound and outbound traffic respectively. Each group lists all the
devices on which rules can be set. You can set rules on all devices at once by clicking
the New Entry link corresponding to 'All Devices'
2. After clicking the appropriate New Entry link, the 'Add Traffic Priority Rule' screen
appears.

3. Under the Matching group, configure the matching characteristics:
a. From the ‘Source Address’ drop-down list, select 'Any', 'User Defined' or the host
as the source address of the packets sent to or received from the network object. If
you have created network objects (see Section 4.5.2 on page 50), then these are
also displayed in the list (or you can create one by selecting ‘User Defined’).
b. From the ‘Destination Address’ drop-down list, select the network object for the
destination address of the packets sent to or received from the network object. See
Step 3 above for a detailed explanation on the options.
c. From the ‘Protocol’ drop-down list, select the protocol. You can apply the rule to all
protocols (i.e., ‘Any’) or select an already defined protocol. You can create a new
protocol by selecting ‘User Defined’, and then following the procedure described in
Section 4.5.3 on page 51.
d. To match DSCP, select the ‘DSCP’ check box, and then enter the DSCP markings.
e. To match priority, select the ‘Priority’ check box, and then select the priority of the
packets.

f. To match the Device, select the ‘Device’ check box, and then select the Device
interface.
g. To match packet or data length, select the ‘Length’ check box, and then enter the
data or packet length.
h. To match connection duration, select the ‘Connection Duration’ check box, and
then enter the duration of the connection (greater or less than).
i. To match connection size, select the ‘Connection Size’ check box, and then enter
the connection size.
4. Under the Operation group, configure the QoS operation:
a. Select the ‘Set DSCP’ check box to mark a DSCP value on packets matching this
rule and then enter the hexadecimal value of the DSCP.
b. Select the ‘Set Priority’ check box to add a priority to the rule and then select the
priority level (where 0 is the lowest and 7 the highest). This sets the priority of a
packet on the connection matching the rule, while routing the packet.
c. Select the ‘Tx Class Name’ check box, and then select the class name that you
defined.
d. From the ‘Apply QoS on’ drop-down list, select whether you want to apply the QoS
rule on the connection or on the packet.
5. Select the ‘Log Packets Matched by This Rule’ check box to log the first packet from a
connection that matches by this rule.
6. From the ‘Schedule’ drop-down list, select the time segments during which the rule may
be active. By default, the rule is always active (i.e., ‘Always’). If you have defined
Scheduler rules (see Section 4.5.1 on page 47), then these are also displayed as
options. To define a new one Scheduler rule, select ‘User Defined’.
7. Click OK to save the settings.
11.4 DSCP Mapping
To understand Differentiated Services Code Point (DSCP), one must first be familiarized with
the Differentiated Services (DiffServ) model. DiffServ is a Class of Service (CoS) model that
enhances best-effort Internet services by differentiating traffic by users, service requirements
and other criteria. Packets are specifically marked, allowing network nodes to provide
different levels of service, as appropriate for voice calls, video playback or other
delay-sensitive applications, via priority queuing or bandwidth allocation, or by choosing
dedicated routes for specific traffic flows.
DiffServ defines a field in IP packet headers referred to as DSCP. Hosts or routers passing
traffic to a DiffServ-enabled network typically mark each transmitted packet with an
appropriate DSCP. The DSCP markings are used by DiffServ network routers to
appropriately classify packets and to apply particular queue handling or scheduling behavior.
MP252 provides a table of predefined DSCP values, which are mapped to 802.1p priority
marking method. You can edit or delete any of the existing DSCP setting, as well as add new
entries.
MP252 Multimedia Home Gateway 124 Document #: LTRT-23504
User's Manual
To view and set DSCP rules:
1. From the menu bar, click the QoS menu link, and then click the DSCP Settings tab; the
following screen appears:

2. To edit an existing entry, click its corresponding Edit icon. To add a new entry, click
the New icon. In both cases, the ’Edit DSCP Settings’ screen appears:
Figure 11-10: Edit DSCP Settings
3. In the ‘DSCP Value (hex)’ field, enter a hexadecimal number for the DSCP value.
4. In the ‘802.1p Priority’ drop-down list, select an 802.1p priority level (each priority level
is mapped to low, medium, or high priority).
5. Click OK to save your settings.
Note: The DSCP value overriding the priority of incoming packets with an unassigned
value (priority 0, assumed to be a no-priority-set) is ‘0x0’. By default, this value is
mapped to 802.1p priority level ‘0 -Low’, which means that such packets receive
the lowest priority.
MP252 Multimedia Home Gateway 126 Document #: LTRT-23504
User's Manual
11.5 802.1p Mapping
The IEEE 802.1p priority marking method is a standard for prioritizing network traffic at the
data link/MAC sub-layer. 802.1p traffic is simply classified and sent to the destination, with no
bandwidth reservations established.
The 802.1p header includes a 3-bit prioritization field, which allows packets to be grouped
into eight levels of priority. MP252 maps these eight levels to three main priorities: high,
medium and low. By default, values six and seven are mapped to high priority, which may be
assigned to network-critical traffic. Values four and five are mapped to medium priority, which
may be applied to delay-sensitive applications, such as interactive video and voice. Values
three to zero are mapped to low priority, which may range from controlled-load applications
down to ‘loss eligible’ traffic. The zero value is normally used for best-effort traffic. It is the
default value for traffic with unassigned priority.
To set 802.1p rules:
1. From the menu bar, click the QoS menu link, and then click the 802.1p Settings tab; the
following screen appears:
Figure 11-11: 802.1p Settings Screen
2. The eight 802.1p values are pre-configured with the three priority levels: high, medium
and low. You can change these levels for each of the eight values in their respective
drop-down list.
3. Click OK to save the settings.

11.6 Class Statistics
MP252 provides accurate, real-time information on the traffic passing through your defined
device classes. For example, the amount of packets sent, dropped, or delayed are just a few
of the parameters that you can monitor per each shaping class.
Note: Class statistics are available only if you have defined at least one class
(otherwise no information is displayed).

11.7 Configuring Basic VoIP QoS
The 'Traffic Shaping' feature only ensures priority to calls that originate from inside MP252.
When giving VoIP priority over data, the bottleneck is effectively moved from the Cable /
ADSL modem into MP252. To give priority to calls from the LAN, you must define a traffic
priority rule (for SIP and RTP from the device on the LAN).
This section recommends a minimal QoS configuration that ensures sufficient QoS for VoIP
calls when MP252 is connected behind a broadband (cable or DSL) modem with limited
uplink bandwidth and the user runs bandwidth-consuming applications on the PC.
Since most modems do not have any priority mechanisms, the Tx bandwidth of MP252
should be limited according to the modem’s uplink bandwidth. Since MP252 automatically
gives higher priority to VoIP packets (in its internal queues), it is not necessary to define
traffic shaping classes.
To configure basic QoS for VoIP:
1. From the menu bar, click the QoS menu link, and then click the Traffic Shaping tab; the
‘Traffic Shaping’ screen appears.
2. Click the New icon; the screen 'Add Device Traffic Shaping' appears.
3. From the 'Device' drop-down list, select 'Default WAN Device' (or your PPTP/L2TP
connection you have created), and then click OK; the 'Edit Device Traffic Shaping'
screen appears.
4. Limit the Tx bandwidth (in the 'Tx Bandwidth' field) according to your modem’s uplink
bandwidth.
5. To prevent jitter in outgoing RTP packets, from the 'TCP Serialization' drop-down list,
select 'Enabled', and then in the 'Maximum Delay' field, define the maximum allowed
delay (e.g. 20 milliseconds). This causes long TCP packets to be fragmented when
there is an active voice call.

12.1 Configuring a WAN Connection
This section describes how to configure your WAN Internet (WAN Ethernet or WAN DSL)
connection.
The WAN connection is configured in the ‘Network Connections’ screen, which provides a
connection wizard that guides you through the network configuration stages.
Notes:
• To quickly configure a basic WAN connection, use the ‘Quick Setup’
screen, as described in Section 7.1 on page 63.
• Before configuring the MP252 Internet connection, ensure that you have
obtained relevant technical information on the Internet connection type from
your Internet Telephony Service Provider (ITSP). For example, whether you
are connected to the Internet using a static or dynamic IP add
ress, or what
protocols such as PPTP or PPPoE are used to communicate over the
Internet.
• MP252 automatically detects the physical WAN type (i.e., Ethernet or
ADSL). To change the WAN type, you must restore MP252 to factory
settings (see Section 18.8).
• When connected to ADSL, the LAN4/WAN Ethernet port can be used for
Ethernet LAN interface.
• When connected to an external modem through the Ethernet LAN4/WAN
port and MP252 obtains an IP address, the ADSL interface is disabled.
•
If the Automatic Dialer feature is shipped preconfigured (i.e., enabled), then
MP252 automatically detects the Internet dialer type and therefore, Internet
connection configuration is unnecessary. However, it is recommended to
manually configure the Internet connection after the Automatic Dialer
process has completed (successfully or not). For more information on the
Automatic Dialer feature, see Section 7.2 on page 72.

Asynchronous Transfer Mode (ATM) is a network technology based on transferring data
in cells or packets of a fixed size. The cell used with ATM is relatively small compared to
units used with other technologies. The small, constant cell size allows the transmission
of video, audio, and computer data, assuring that no single type of data consumes the
connection. ATM addressing consists of two identifiers that identify the virtual path (VPI)
and the virtual connection (VCI). A virtual path consists of multiple virtual channels to
the same endpoint.

Asynchronous Transfer Mode (ATM) is a network technology based on transferring data
in cells or packets of a fixed size. The cell used with ATM is relatively small compared to
units used with other technologies. The small, constant cell size allows the transmission
of video, audio, and computer data, assuring that no single type of data consumes the
connection. ATM addressing consists of two identifiers that identify the virtual path (VPI)
and the virtual connection (VCI). A virtual path consists of multiple virtual channels to
the same endpoint.

12.2.1.3.5 Configuring Transmission Properties
The procedure below describes how to configure wireless transmission properties.
To configure the transmission properties:
1. Access the Wireless tab screen.
Figure 12-47: Transmission Parameters in Wireless Tab Screen
2. From the ‘CTS Protection Mode’ drop-down list, select whether you want to enable or
disable this feature (‘Always' to enable CTS or 'Auto' to have MP252 automatically
decide whether or not to use this feature). CTS Protection Mode boosts your MP252's
ability to intercept 802.11g and 802.11b transmissions. Conversely, CTS Protection
Mode decreases performance. Leave this feature disabled unless you encounter
severe communication difficulties between MP252 and 802.11g products.
3. In the ‘Beacon Interval’ field, enter how often the beacon packet is sent. A beacon is a
packet broadcast by MP252 to synchronize the wireless network.
4. In the ‘DTIM Interval’ field, enter the Delivery Traffic Indication Message (DTIM)
countdown value that informs wireless clients of the next opportunity to receive
multicast and broadcast messages. This value ranges between 1 and 16384.
5. In the ‘Fragmentation Threshold’ field, enter the packet size threshold above which
packets are fragmented into multiple packets. Try to increase the fragmentation
threshold if you encounter high packet error rates. Do not set the threshold too low,
since this can result in reduced networking performance.
6. In the ‘RTS Threshold’ field, enter the packet threshold size below which the Request to
Send (RTS) / Clear to Send (CTS) mechanism are not active. MP252 sends RTS
packets to the wireless client to negotiate the dispatching of data. The wireless client
responds with a CTS packet, signaling that transmission can commence. If you
encounter inconsistent data flow, try a slight reduction in the RTS threshold size.
12.2.1.3.6 Adding Virtual Access Points
You can set up multiple virtual wireless LAN's on MP252, limited. Such virtual wireless LANs
are referred to as "Virtual APs" (virtual access points). In the Wireless tab's screen, under
the section 'Virtual APs' section, MP252's physical wireless access point is displayed first,
and on top of which virtual connections may be created.
Figure 12-48: Virtual APs Table
MP252 Multimedia Home Gateway 12. Network Connections
Version 3.4.0 163 June 2011
To create a virtual connection:
1. In the Wireless tab's screen, under the section 'Virtual APs' section, click the New
Virtual AP link; the screen refreshes, displaying the new virtual connection.
Figure 12-49: New Virtual AP
The new virtual connection is also added to the list of connections in the 'Network
Connections' screen (Network Connections menu), and is configurable like any other
connection (by clicking its corresponding Edit icon).
A useful implementation of Virtual AP's is to define a virtual connection with a different SSID
value to dedicate it for guest access. Through this connection, guests are able to access the
WAN, but they are denied access to other wireless LANs provided by MP252. To do so,
perform the following:

Parameter Description
Routing Select 'Advanced' or 'Basic' routing.
Routing Mode Select one of the following Routing modes:
Route: Use route mode if you want your device to function as a router
between two networks.
NAT:
Network Address Translation (NAT) translates IP addresses to a valid,
public address on the Internet. This adds security since internal LAN
addresses are not transmitted over the Internet. In addition, NAT allows
many addresses to exist behind a single valid address. Use the NAT routing
mode if your LAN consists of a single device, otherwise collisions may occur
if more than one device attempts to communicate using the same port.
NAPT: Network Address and Port Translation (NAPT) refers to network
address translation involving the mapping of port numbers, allowing multiple
machines to share a single IP address. Use NA
PT if your LAN encompasses
multiple devices, a topology that necessitates port translation in addition to
address translation.
Device Metric The device metric is a value used by
the device to determine whether one route
is superior to another, considering parameters such as bandwidth, delay, and
more.
Default Route Select this check box to define this device as a the default route.
Multicast IGMP Proxy Internal IGMP proxy enables the system to issue IGMP host
messages on behalf of hosts that the system discovered through standard IGMP
interfaces. IGMP proxy enables the routing of multicast packets according to the
IGMP requests of LAN devices asking to join multicast groups. Select the
'Multicast IGMP Proxy Internal' check-box to enable this feature.
Routing Table Allows you to add or modify routes when this device is active. Use the New
Route button to add a route or edit existing routes.

MP252 Multimedia Home Gateway 13. Remote MP252 Management
13 Remote MP252 Management
This chapter provides an overview of the MP252 remote configuration and management
support. In addition, this chapter describes how to enable and secure remote management,
as well configure MP252 through SNMP and TR069.
13.1 Overview
MP252 is designed to be mass-deployed. One of the keys to guarantee end-user satisfaction
and true toll-quality service in mass field deployment is comprehensive remote configuration
and management capabilities:
Automatic and remote configuration updates
Automatic and remote firmware updates
Remote diagnosis of problems reported by the user
Remote collection of statistical information regarding the quality of the service
Remote notifications of problems in the service
13.1.1 Remote Configuration
By default, MP252 is provided with factory default settings, which are common to all MP252
devices (except for the MAC address). The factory settings allow the user to connect to
MP252's Web interface through the LAN.
By default, the WAN interface is configured for DHCP (i.e., automatically obtains its IP
address from a DHCP server). The default configuration should not include any VoIP service
provider settings (such as a SIP proxy).
In some cases, AudioCodes can ship MP252 devices that are pre-configured with some
customer-specific parameters. This set of parameters is usually defined as the new "factory
settings" for the specific customer.
MP252's factory default settings and the current configuration running on MP252 are stored
on MP252's non-volatile flash memory. The current configuration can be remotely updated
using several configuration interfaces:
HTTP-based Web server
SNMP
TR-069
Configuration file upload/download
MP252 Multimedia Home Gateway 194 Document #: LTRT-23504
User's Manual
Figure 13-1: Remote Management Interfaces
All configuration interfaces access the same internal configuration repository. The
configuration file represents the complete set of MP252 configuration parameters. Specific
configuration interfaces (e.g. SNMP and TR-069) might support access only to a sub-set of
these configuration parameters.
At any time, the factory settings can be restored using the Web interface or by pressing the
Reset pin-hole button while MP252 is being powered up.
The table below lists the main MP252 configuration parameter groups:
Table 13-1: Main Configuration Parameter Groups
Group Description
VoIP Parameters relating to the VoIP functionality (e.g. analog interface, SIP
signaling, voice and fax, media streaming)
WAN Interface The main WAN Internet connection (this group is also referred to as the
"Quick Setup").
Network Connections Configuration of all network connections (LAN and WAN), including
advanced connections such as VLANs.
Security Parameters relating to the internal firewall.
QoS Configuration of Quality of Service parameters such as priorities and traffic
shaping.
System / Advanced Configuration of system parameters such as Remote Update and Remote
Access and advanced parameters such as Dynamic DNS, UPnP.
A typical set of parameters that a service provider may want to configure include the
following:
Remote access and/or automatic firmware and configuration update parameters
VoIP configuration: SIP proxy, line settings (User IP, Password)
QoS parameters (e.g. traffic shaping)
13.1.2 Remote Management
MP252 Multimedia Home Gateway 13. Remote MP252 Management
Version 3.4.0 195 June 2011
Remote management includes the following:
Firmware upgrade
Status and performance monitoring
Alarms, notifications, and logs
13.1.2.1 Firmware Upgrade
Service providers require the ability to update MP252's firmware in the field (e.g. in case of
maintenance releases or releases that support new required features). The process is
required to be automatic, allowing mass update, which is robust and fail-safe.
MP252's firmware is stored on the non-volatile flash memory. MP252's flash memory is
capable of storing a recovery firmware that ensures a fail-safe operation (even if the user
unplugs the power during the firmware burning process).
MP252's firmware can be upgraded using one of the following mechanisms:
The new firmware can be "pushed" (uploaded) to MP252, using the MP252 Web
interface
The new firmware can be "pulled" (downloaded) by MP252 from a remote HTTP, FTP,
or TFTP server
Figure 13-2: Firmware Upgrade Mechanism
MP252 Multimedia Home Gateway 196 Document #: LTRT-23504
User's Manual
The remote firmware download process can be triggered by one of the following:
MP252 checks for a new firmware upon MP252 restart
MP252 periodically checks for a new firmware
Manual trigger using CLI, TR-069, SNMP or Web
Note: Unless forced, MP252 downloads and upgrades to the new firmware only if its
version number is higher than the firmware version currently running on MP252.
The version number is not taken from the image file name, but from the header
of the image file.
13.1.2.2 Status and Performance Monitoring
The ability to remotely monitor the status of MP252 is critical to the service provider, who
wants to support users without having to send a technician on site (avoiding the "truck roll").
The service provider may want to know the current status of MP252 (e.g. is it registered to
the SIP proxy, is the phone off-hook) or some statistical information (e.g. average packet loss
during a call).
MP252 maintains a set of status and performance information internally. This information (or
parts of it) can be retrieved via the different management interfaces (e.g. Web, or TR-069).
The table below describes the status and performance monitoring (statistical) information
available in MP252.
Table 13-2: Status and Performance Monitoring Parameters
Group Description

Version 3.4.0 197 June 2011
13.1.2.3 Alarms, Notifications and Logging
Instead of periodically polling MP252 to obtain its current status, the service provider may
want MP252 to notify abnormal events or to send regular reports to a logging server. Both
options are supported by MP252. The table below lists the relevant interfaces for alarms and
notifications.
Table 13-3: Notifications and Logged Events
Group Notifications and Logged Events
VoIP
Notifications: Registration error or timeout
Logged Events:
End of call (Call Detail Record logging)
SIP messages logging (optional - for debugging)
Network Connections
Notifications: Connection up / down
Security
Logged Events: Security log (configurable)
System
Notifications:
System restart
Firmware / configuration update
Logged Events: Debug-level logging (optional)
Note that the terms Alarm and Notification represent the same thing. The difference between
alarm/notification and logging is that an alarm is normally used to represent an abnormal
event (e.g. registration error), while logged events can represent either regular events (e.g.
end of call) or abnormal events.
The table below lists the event severity levels defined in MP252. Typically, events with
severity of Error or Emergency are notified in addition to being logged.
Table 13-4: Severity of Logged Events
Severity Description
Debug Debug-level messages.
Notice Normal but significant condition. Notices requiring attention at a later time.
Non-error conditions that might require special handling.
Error Recoverable / temporary error condition.
Emergency
System is unusable. The most severe messages that prevent continuation of
operation, such as immediate system shutdown.
13.2 Enabling Remote Management
You can access and manage MP252 not only from within the home network, but also from
the Internet. This allows you to view or change settings while travelling. It also enables you to
allow your ISP to change settings or help you troubleshoot functionality or communication
issues from a remote location.
Remote access to MP252 is blocked by default to ensure the security of your home network.
However, remote access is supported by the following services, and you may use the
'Remote Access Configuration' screen to selectively enable these services if they are
needed.
MP252 Multimedia Home Gateway 198 Document #: LTRT-23504
User's Manual
Notes:
• Telnet and Web-Management can be used to modify the settings of the
firewall or to disable it. You can also change local IP addresses and other
settings, making it difficult or impossible to access MP252 from the home
network. Therefore, remote access to Telnet or HTTP services should be
blocked and should only be permitted when absolutely necessary.
• Encrypted remote administration is done using a secure SSL connection
that requires an SSL certificate. When accessing MP252 for the first time
using encrypted remote administration, you are prompted by your browser
with a warning regarding certificate authentication. This is because
MP252's SSL certificate is self generated. When encountering this
message under these circumstances, ignore it and continue. It should be
noted that even though this message appears, the self-generated
certificate is safe, and provides you with a secure SSL connection. You
can also assign a user-defined certificate to MP252.
To enable remote access to MP252 services:
1. In the 'Advanced' screen, click the Remote Administration icon; the 'Remote
Administration' screen appears.

2. Select the services that you would like to make available to computers on the Internet.
• Allow Incoming WAN Access to Web-Management: Allows access (from a Web
browser) to the Web management interface and to all system settings and
parameters. Both secure (HTTPS) and non-secure (HTTP) access is available.
• Allow Incoming WAN Access to the Telnet Server: Allows access to the
command-line session and to all system settings and parameters (using a
text-based terminal).
• SNMP: Allows Simple Network Management Protocol (SNMP) requests to
remotely configure and monitor MP252.
• Diagnostic Tools: Allows remote access for ping and traceroute (over UDP)
troubleshooting.
• TR-069: TR-069 is a WAN management protocol for communication between
Customer Premise Equipment (CPE) and an Auto-Configuration Server (ACS). It
defines a mechanism that encompasses secure auto-configuration of a CPE, and
also incorporates other CPE management functions into a common framework.

13.3 Securing Remote Management with Certificates
The Certificates icon allows you to configure certificates. When a service provider
implements remote provisioning in which a unique configuration file (per MP252) is placed on
a server located on the WAN, the service provider can ensure that only its deployed MP252
units are able to connect to the HTTP server via HTTPS. This is performed by using a
certification validation process (client-server).
There are two types of certificates:
Self-signed certificates
Certificate Authority (CA) signed certificates
The procedure below describes how to operate with self-signed certificates.
To operate with self-signed certificates:
1. In the 'Advanced' screen, click the icon; the 'Certificates' screen appears.
Figure 13-4: New Certificates Screen
2. Create a self-signed certificate:
Note: You can also create a self-signed certificate using the OpenSSL utility,
downloaded from http://sial.org/howto/openssl/self-signed.
a. Select the MP252’s Local tab.
b. Click the Create Self Signed Certificate button; the 'Create Self Signed X509
Certificate' screen appears.
